Detection and morphology of hyphae of common bunt fungi (Tilletia laevis and T. tritici) in wheat seedlings

Transactions of the British Mycological Society, 1987
A technique was developed to detect hyphae of the common bunt fungi ( Tilletia laevis and T. tritici) in wheat seedlings. This accurately predicted the subsequent incidence of bunted heads in two field trials. Details of the morphology of Tilletia hyphae in leaf-sheath tissues are given.

Resistance of winter wheat cultivars to common bunt, Tilletia tritici (Bjerk.) Wint. and T. laevis Kühn

Journal of Plant Diseases and Protection, 2006
The resistance of 90 European commercial winter wheat cultivars and advanced lines was tested after inoculation with common bunt. Out of it 27 cultivars/lines showed bunt incidence below 25% at least in one trial. The results obtained were compared with results published by other authors.

Identification of new wheat common bunt pathotypes (Tilletia laevis Kuhn.).

Communications in agricultural and applied biological sciences, 2007
Common bunt (CB) is the most important wheat disease after the rusts and the development of bunt-resistant cultivars is one of the best methods to control the disease. To identify new sources of resistance genes, identification of different pathotypes of this disease is essential. For this purpose, 449 isolates of CB collected from rainfed wheat fields

A comparison of polypeptides from the wheat bunt fungi Tilletia laevis, T. tritici, and T. controversa

Canadian Journal of Botany, 1988
Phenol-soluble polypeptides were extracted from teliospores of six races of each of Tilletia laevis and T. tritici, and eight collections of T. controversa. The polypeptides were separated by two-dimensional isoelectric focusing – polyacrylamide gel electrophoresis and the resulting patterns compared.

Effects of seeding date and cultivar susceptibility on effectiveness of carbathiin for control of common bunt (Tilletia tritici and T. laevis) in winter wheat in southern Alberta

Canadian Journal of Plant Pathology, 1994
L'efficacite de carbathiine (carboxine) a traiter des semences de ble d'hiver artificiellement infectees avec la carie commune (Tilletia tritici et T. laevis) a ete evaluee sur trois varietes, onze dates d'ensemencement de 1989-1992 et trois taux d'applications (0,55, 0,76, et 1,1 g ia/kg).

Reaction of winter wheat cultivars registered in the Czech Republic to common buntTilletia tritici(Bjerk.) Wint. andT. laevisKühn

Cereal Research Communications, 2006
Results of the tests for bunt resistance of the cultivars registered in the Czech Republic and older Czech and Slovak cultivars carried out from 1988 to 2005 are presented. In most experiments mixture of samples of T. tritici and T. laevis from different locations was applied for inoculation.

Inhibition ofTilletia laevisTeliospore Germination and Suppression of Common Bunt of Wheat byPseudomonas fluorescens2-79

Plant Disease, 1993
A rifampicin-resistant derivative of Pseudomonas fluorescens strain 2-79 (Pf2-79r) inhibited teliospore germination of Tilletia laevis. A rifampicin-resistant derivative of a spontaneous mutant of strain 2-79 deficient in phenazine-1-carboxylic acid production (2-79PCA - r) had no effect on germination of T. laevis. Inhibition of germination by Pf2-79r

Genome sequencing, phylogenomics, and population analyses of Tilletia , with recognition of one common bunt species, T. caries (synonym T. laevis ), distinct from dwarf bunt, T. controversa

Mycologia
Some species of Tilletia are responsible for diseases in economically important crops, such as wheat and rice. In this study, we sequenced, assembled, and annotated 22 new genomes for Tilletia, with a focus on species causing dwarf bunt (DB; T. controversa), common bunt (CB; T. caries and T. laevis), and rice kernel smut (RKS; T. horrida).

Effect of seed treatment with organic acids on the control of common bunt (Tilletia tritici and T. laevis) in wheat.

Mededelingen (Rijksuniversiteit te Gent. Fakulteit van de Landbouwkundige en Toegepaste Biologische Wetenschappen), 2003
Common bunt caused by Tilletia tritici and T. laevis is an important disease, causes considerable losses in wheat yield on a world wild. The disease reduces yields, complicates harvesting and lowers the quality of the grain. It occurs more frequently and causes greater damage on winter wheat than on spring wheat.
